Pros: I got this KB for work. I have Carpel Tunnel, and work in IT, so doing lots of typing on a standard KB gets real painful after a short while. They curve and layout of this KB is very nice. And having the full number keypad is also very nice. I personally do not use all the keys across the top, but they are still nice to have.

Cons: Only negative for me, is that the palm rest is solid plastic. Knew it when I ordered it, but for the price I cannot complain.

Pros: Good ergonomics

Cons: My 5 key feels like there is a paper clip stuck under it, even though there is nothing there. Function keys are useless. For example, if you hit the Vol+ or Vol- key once, it will continue to send the signal until you disconnect the keyboard. If you hit the "favorites" button, the "home" or "E-mail" keys will not work until you disconnect and reconnect the keyboard.

Pros: 1. Mechanical keys, they pop right off and you can clean under them. not that I do that ever..

2. Same layout as the Belkin that went extinct. I NEED this layout to type properly. It's supreme for reducing RSI. I've had close calls with carpal tunnel in the past, this keyboard cured my pain.

3. Large spacing on the keys and large keys for those of us with big hands.

4. wrist rest for more comfort even if it is plastic.

5. Very good coating on the keys, I've only worn out the M key in four years. Other keys are getting shiny though. but the letters/numbers are still there, not that I need to see them.

Cons: 1. Plastic/chincy feel ( it's still comfortable and the rigid plastic makes it durable and bacteria resistant)

2. loud plastic key sounds. (not a problem in my book, when you're typing fast any keyboard will make sounds)

3. no G-keys, I love gaming and I just can't get myself to use one of those so called "Gaming" keyboards, because they are flat even the ones that claim ergo are liars and I want to slap them for putting the word ergonomic on a keyboard that is NOT. Sadly adesso will probably never make a gaming version of this board but I can dream.

4. Rubber anti-slip feet came off of two of the five spots. Other than being a bit more slippy, this hasn't affected performance. I could have super glued them back on but I lost them before I got around to it, haha.

5. SLEEP/SHUTDOWN keys are a PITA. I've accidentally hit them several times and I finally broke down and melted the keys in their resting position. You can't remove the media or sleep/wake/power buttons. (silver ones) so if you don't want to keep hitting them on accident just melt them with a lighter or blowtorch. I personally hate media keys and sleep/shutdown keys on keyboards.

Other Thoughts: Not sure what else to say other than, I am going to be ANGRY when they stop making split keyboards that are truly ergonomic. This keyboard is at least the right layout and feels good to type on for hours on end. It's lasted over four years for me. It really is spill-proof and I've extensively accidentally tested this. I may have to buy another soon just because I get ants on it in the summer and fall because of all the food and drink I've spilled in it, but it keeps going and I still love it! there's a PRO tag, "ANT PROOF." I also have never had a problem with bacteria but I do wipe off the keys occasionally with ammonia/water. I hope in some way I answered your questions about this board. I would recommend this board to a friend and until they make truly Ergo gaming boards I'll keep my adesso.

Pros: Very good ergonomic shape. Great wrist rest. Keyboard elevation and wrist rest keep wrists at a flatter angle than standard keyboards. Very good key response -- positive click rather than mushy. Multimedia controls are very handy.

Cons: I only have one of these...

Other Thoughts: I've been using this keyboard for 3-4 years and it has been great. No problems with keys, I can type extremely fast, and my wrists never hurt. I may go home from work with a stress headache every night, but I don't have to worry about carpal tunnel syndrome with this keyboard!

Pros: Wonderful ergonomics and feel. Allows me to be more creative.

Cons: None.

Pros: Configuration! Same configuration as my old belkin ergonomic that I love...

Cons: Number pad just went out....

Other Thoughts: The belkin lasted for years...not months but I do use this all day at work. Now time to try another...wish belkin still made that one...no one makes a good ergonamic in this configuration... This one is laid out perfectly...but made cheaply.

Pros: Price

Cons: After 6 months certain key's stopped working. This keyboard feels/looks cheap!

Pros: Extremely quiet compared to the microsoft natural ergo. The split spacebar is great and avoids the sticking problem so many ergonomic keyboards have. Hotkeys are honestly better than the microsoft natural ergo

Cons: Quality control is pathetic. I own two of these keyboards, each of which 1-3 keys that almost get stuck or doent really give feedback when pressed.

Other Thoughts: If the key mechanisms were a little higher quality this thing would be perfect.

***CURRENT MODELS SOLD BY NEWEGG HAVE NORMAL SIZE ENTER AND BACKSPACE KEYS!!!!!!!*******

Pros: It looked nice on newegg website

Cons: low quality workmanship... poor materials used... cheap feeling, keys fell off lifting it out of the box on 1 of the 2 we bought... the other was DOA... and the Enter keys were stuck in a permanent down position. Thank you newegg for being so good at refunds.

Pros: Comfortable hand and arm position, about 1/10th as noisy as the Microsoft Natural Ergonomic Keyboard 4000, lots of marks on the sides of the keys to clue you into hot keys you might not normally use, great value for the price

Cons: None so far

Other Thoughts: I purchased the Microsoft Natural Ergonomic Keyboard 4000 for work, where I input data for a website. While most of the keys were quiet, the space bar stuck every time I hit it. My coworkers ask that I replace it. I purchased the Adesso sight unseen. I guess because they split the space bar in half, that avoided the problem the Microsoft had. I like it so much I'm about to buy another one for home. I can't tell you how happy I am to have a keyboard that doesn't leave my forearms aching ever day when I leave work, and that is quiet. I use a Mac at work and all I had to do to configure the keyboard was push the "Z" key, and then the "/" key. This thing is tops.
